The charging pile fuse is a current protector based on the principle that after the current exceeds the specified value for a period of time, it will melt the melt with the heat generated by itself, so as to disconnect the circuit. Fuses are widely used in low-voltage distribution systems, control ... Read More

According to the Breakthrough Agenda report released by the International Energy Agency (IEA), global progress on net-zero transport falls short of the Paris Agreement goals. By the end of 2021, zero-emission vehicles will account for less than 1% of the global car fleet. The IEA believes that by ... Read More

Some precautions in the use of fuse 1. The rated voltage of the fuse should be greater than the input voltage of the protected circuit. 2. The rated current of the UL specification fuse is determined under laboratory conditions. The actual use should be less than 75%of the nominal value. 3. The ... Read More

The impact on use after the fuse aging After the fuse is aging, the danger of cutting the current without the fuse is not melted. The aging of fuse is equivalent to the decline of the rated value (current) rather than rising, causing the circuit to cut off the circuit at a small overload current or ... Read More

Factors affecting the life of the fuse Working temperature: Excessive ambient temperature is damaged in the life of the fuse. The delay type (slow melting) fuse is like a tin ball type, and the temperature starts to spread to the metal wire when the temperature is about 150 ~ 170 ° C); 175 ~ 225 ° C... Read More

The voltage rated value of the fuse must be greater than or equal to the maximum voltage of the disconnect circuit. For example, if the working voltage is 120V, the rated voltage of 250V may be required; because the resistance value of the fuse is very low, the voltage rated value of the fuse is ... Read More
